Oregon Scientific collisions

Hi,

I know it's due to the protocol, but I would like to understand how often you guys have collisions with OS sensors. Also i have noticed although the battery still reports to be fine, changing it with fresh ones seems to give a better result.

For some reason I'm having this a lot the last weeks with 3 of my 12 Oregon Scientific units!
They are about 1/2 year old, so I do not think that this is a battery problem.
After some time all will be fine again, but than suddenly it's bad again.

I have 10 THGR228N sensors locate througout the house, a BWR102 scale and some other X10 RF stuff.

Once in a while I am missing data from some sensors. Although I made sure when inserting the batteries that two sensors would not transmit at the same time, in time two (or more) will start transmitting synchronously and I will miss data. This normally lasts for a few hours.

When I insert the batteries in a sensor, I look at the rfxcom logfile that my application generates about every received packet and make sure to insert the battery in the middle of the longest interval between two transmissions.

Regaring changing batteries, I normally do this when the sensor starts telling me the batteries are empty. I have not noticed any RF issues due to a low-battery condition.
